SCREENING FOR OPTIMAL YIELD IN THE CRYSTALLISATION OF MULTICOMPONENT SYSTEMS

摘要

A method of determining the optimal yield of a target compound comprises: (a) determining the initial composition of a mixture of compounds containing the target compound; (b) dissolving the mixture in a solvent; (c) placing a quantity of the solution in a plurality of vessels; (d) optionally, placing a portion of a different derivatising agent in each vessel; (e) causing crystallisation to occur; (f) analysing the contents of the vessels after the crystallisation has approached equilibrium to determine the compositions of the liquors and the compositions of the solids; and (g) comparing the compositions determined in step (f) to profile the performance of each system (by calculated means) in terms of the projected maximum yield of target compound is an optimised crystallisation process.
